- Eighteen companies involved in modem development and manufacturing last
- week said they have formed a consortium to promote a new high-speed modem
- modulation scheme called V.32terbo.
- The new scheme will allow modems to operate at 19.2 kilobits per
- second. V.32terbo-compliant modems will interoperate, according to the
- consortium.
- The group will publish specifications of the scheme so that other
- companies can build products compatible with the standard.
- Some consortium members plan to announce V.32terbo-compliant modem
- products as early as next quarter.
- The breakaway move by these companies comes in response to the need
- for high-speed modems that can operate faster than existing V.32bis
- standard modems, which have a data throughput of 14.4 Kbps.
- V.fast, a proposed modem standard that would allow such devices to
- interoperate at speeds of up to 28.8 Kbps, is currently under development
- by the International Telegraph and Telephone Consultative Committee. But
- progress on the standard has been slow, and industry experts who attended a
- CCITT meeting on V.fast in Geneva earlier this month do not expect work on
- the standard to be completed until mid-1994.
- The V.32terbo scheme grew out of a proposal made at the CCITT's
- meeting last September by AT&T, National Semiconductor Corp. and Penril
- DataComm Networks Inc. The proposal which was voted down, had called for
- the committee to approve an interim standard called V.32ter that would
- allow modems from different vendors to interoperate at 19.2 Kpbs.
- According to Dick Stuart, vice president of technology for Penril
- DataComm Networks, Gaithersburg, Md,. his company and other companies
- involved in the V.32terbo group will start announcing products based
- on the V.32terbo scheme in the second quarter. In the near future,
- several major modem players not affiliated with the new consortium also
- will announce V.32terbo-compliant product, Stuart said.
- General DataComm Inc., Motorola Codex and Racal Datacomm Inc.
- opposed the V.32terbo proposal. According to Julio Siberio, division vice
- president at Racal Datacom, Sunrise, Fla., the opposing group will announce
- next month at the ComNet show plans to stick with the pending V.fast
- standard.
- General DataComm, Mototola Codex and Racal Datacom have all
- announced plans to ship proprietary versions of V.fast. Motorola Codex,
- Mansfield, Mass., starte shipping a V.fast modem in May 1992.
